Aanleiding voor het uitvoeren van het archeologisch onderzoek vormt de aanvraag van een omgevingsvergunning voor bouw van 20 nieuwe woningen. Uit het vooronderzoek is gebleken dat het plangebied in een dalvakteterras ligt rondom opgestoven landduinen langsheen de Maas. De bodem bestaat volgens de bodemkaart uit vorstvaaggronden. Het plangebied is in het verleden voor zover kon worden vastgesteld in gebruik geweest als bouwland en is niet bebouwd geweest. Het IVO-O heeft uitgewezen dat de bodemopbouw deels intact is, al lijken in sommige boringen sporen van vergravingen of verstoringen te bevatten. Op grond van de resultaten van het vooronderzoek is een hoge verwachting opgesteld op het voorkomen van archeologische waarden uit het paleolithicum tot aan de vroege middeleeuwen. Voor de periode late middeleeuwen en nieuwe tijd is een lage verwachting opgesteld. Op grond van de resultaten van het vooronderzoek is een IVO-P uitgevoerd. Hierbij is een vindplaats aangetroffen bestaande uit drie subrecente greppels en een tweetal recente verstoringen. De vindplaats is als niet behoudenswaardig gewaardeerd. Aanbevolen is het plangebied vrij te geven voor de geplande ontwikkeling."}], "title": [{"qualifier": {"classid": "main title", "classname": "main title", "schemeid": "dnet:dataCite_title",

Aanleiding voor het uitvoeren van het archeologisch onderzoek vormt de aanvraag van een omgevingsvergunning voor bouw van 20 nieuwe woningen. Uit het vooronderzoek is gebleken dat het plangebied in een dalvakteterras ligt rondom opgestoven landduinen langsheen de Maas. De bodem bestaat volgens de bodemkaart uit vorstvaaggronden. Het plangebied is in het verleden voor zover kon worden vastgesteld in gebruik geweest als bouwland en is niet bebouwd geweest. Het IVO-O heeft uitgewezen dat de bodemopbouw deels intact is, al lijken in sommige boringen sporen van vergravingen of verstoringen te bevatten. Op grond van de resultaten van het vooronderzoek is een hoge verwachting opgesteld op het voorkomen van archeologische waarden uit het paleolithicum tot aan de vroege middeleeuwen. Voor de periode late middeleeuwen en nieuwe tijd is een lage verwachting opgesteld. Op grond van de resultaten van het vooronderzoek is een IVO-P uitgevoerd. Hierbij is een vindplaats aangetroffen bestaande uit drie subrecente greppels en een tweetal recente verstoringen. De vindplaats is als niet behoudenswaardig gewaardeerd. Aanbevolen is het plangebied vrij te geven voor de geplande ontwikkeling."}], "format": [], "coverage": [], "externalReference": [], "publisher": {"dataInfo": {"invisible": false, "provenanceaction": {"classid": "sysimport:crosswalk:repository", "classname": "Harvested", "schemeid": "dnet:provenanceActions", "schemename": "dnet:provenanceActions"}, "trust": "0.9", "inferred": false, "deletedbyinference": false}, "value": "Data Archiving and Networked Services (DANS)"}, "context": [], "eoscifguidelines": [], "language": {"classid": "und", "classname": "Undetermined", "schemeid": "dnet:languages", "schemename": "dnet:languages"}, "resulttype": {"classid": "dataset", "classname": "dataset", "schemeid": "dnet:result_typologies", "schemename": "dnet:result_typologies"}, "country": [], "extraInfo": [], "originalId": ["oai:easy.dans.knaw.nl:easy-dataset:341200", "50|r3730f562f9e::ace629fb505b6b4343faca03edde1841"], "source": [], "dateofacceptance": {"dataInfo": {"invisible": false, "provenanceaction": {"classid": "sysimport:crosswalk:repository", "classname": "Harvested", "schemeid": "dnet:provenanceActions", "schemename": "dnet:provenanceActions"}, "trust": "0.9", "inferred": false, "deletedbyinference": false}, "value": "2024-01-01"}, "title": [{"dataInfo": {"invisible": false, "provenanceaction": {"classid": "sysimport:crosswalk:repository", "classname": "Harvested", "schemeid": "dnet:provenanceActions", "schemename": "dnet:provenanceActions"}, "trust": "0.9", "inferred": false, "deletedbyinference": false}, "qualifier": {"classid": "main title", "classname": "main title", "schemeid": "dnet:dataCite_title", "schemename": "dnet:dataCite_title"}, "value": "Archeologisch onderzoek IVO-P plangebied Heijackerstraat te Beesel"}]} \ No newline at end of file
